SPECIFICATION forming part of Letters Patent N o. 588,480, dated August 1'7, 1897. Application iiled May 17, 1897. Serial No. 636,888. (No model.)

To all whom, it mfc/ 7j concern: f

Be it known that I, DIDRIKs R. Ross, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Ships-Port Ventilators; and I hereby dethe accompanying drawings, in which- Figure l is a detached view of my ventilator. Fig. 2 is a vertical section of my dev1ce.

The object of my invention is to provide a removable attachment for Windows or port-s of vessels which, while allowing of a sufiicient opening for light and air, is so constructed as to prevent the ingress of Water either dashed against the vessel in the form ofspray or by waves or rain.

The present illustration shows my device adapted to be applied to the ordinary circular ports which are made in the vessels sides and are usually closed by heavy glass bullseyes, so that light will be admitted, while the rain and wet are kept out, but this also prevents any ingress of air, and the rooms often become close and foul, especially where there are successive days of stormy Weather.

In m-y invention I have shown a tortuous tube or passage A, having at the lower end a tubular flange B, which is adapted to fit into the port-opening and may have a surrounding soft packing-ring, as shown at C, vso that when inserted it will t and make a close joint with the interior surface of the port, the Vbullseye being unscrewed or otherwise removed so as to leave the opening free for the introduction of this flange. This flange opens into the rst section of the tube or passage, which is vertical, extending upwardly a short distance, thence an approximately horizontal or diagonal portion A extends outwardly to the side opposite to that on which the flange B projects, and thence the tube makes another turn and extends vertically upward, as shown atA2. This second portion A2 is sufficiently out of line with the part A to prevent any ingress of water which might be dashed into the part A and splashed upwardly, as 'the top of the diagonal portion A acts as a stop to prevent the'water passing any farther, and it subsides from this point and flows out again through the tubular flange B and the port, While the passage remains open for the ingress of air, so as tov give a good ventilation to the apartment.

In some cases where the weather is unusually rough and it is still desirable to have y the Ventilating-opening I employ a supplemental tube D, which is adapted to slip into the part A2 and may be supported by lugs or outwardly-turned fianges d upon its upper end. Vithin this tube are iixed diaphragms E, which incline in opposite directions alternately from the sides of the tube, so that in case of any unusual dashing of water into the port which might carry it up into the part A2 these diaphragms Will serve to stop it and prevent its passing entirely out of the top of this portion of the tube.

The part D being removable. can be used or not, as may be desired.

Upon the side ot' the part A which is in line with and opposite the port and the flange B, I may set in a bulls-.eye or glass of sufcient strength, which is hermetically sealed to prevent any passage of water through this portion, but allows the light to enter the cabin in the same way that it will through the usual port bulls-eye. If the movement of the air is faint, and in hot climates, where the movement of the vessel may produce a little draft,

I employ a directing device, which consist-s of a semicircular or other suitably-shaped device y IOO caved face in that direction; but if the breeze comes from the bou7 or is produced by the movement of the vessel through the Water it will be reversed and turned in the opposite direction.

The whole device is easily inserted or removed at pleasure and is adjustable to suit the character of the weather.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent7 is l. A ships-port ventilator consisting of a tubular tortuous passage adapted to project upwardly Within the apartment into which the port opens, and a tubular flange projecting therefrom adapted to t and form a tight joint within the port-opening.

2. A ships-port ventilator consisting of a tortuous tubular passage having a flange and packing whereby the fiange forms a tight joint with the port-opening, and a supplemental extension fitting the tubular flange, projecting exteriorly so as to direct the current of air into the device.

3. A ships-port ventilator consisting of a tortuous passage formed bythe union of two vertical passages by a diagonal one connecting them out of line With each other, atubular flange With packing adapted to fit and form a tight joint in the port-opening and a supplemental removable tube fitting the upper portion of the main tube with means for suspending it therein, and diagonally-disposed diaphragms projecting alternately from opposite sides.

4. A ships-port ventilator consisting of a tortuous passage formed by the union of a plurality of vertical tubes and a diagonal connecting-tube, a tubular flange projecting outwardly from the lowermost section adapted to form a tight joint with the port-opening, and a glazed light-opening formed in the opposite side of the vertical tube in line with the tubular flange.

In witness whereof l have hereunto set my hand.
